Dana rear, WIW?

I'm helping a good friend sell off his cache of small and big block ( Chevy) , yeah, I know..lol. parts. In his garage he has a Dana 60 that's narrowed. Has 5.38 gears and Summers Brothers axles. I haven't pulled the pan yet to see the gears or what spool ( I assume) it has. I have the dimensions in the pics. It comes with "ladder bars" .

He had a Super Gas 57 Chevy and a rail that he raced. Idk what this was built for, but I'm sure it would work in multiple applications/vehicles.
Any help to determine a price would be greatly appreciated!
Thanks FABO!
